Class VideoIntelligence

java.lang.Object

org.apache.beam.sdk.extensions.ml.VideoIntelligence

public class VideoIntelligence
extends Object

Factory class for PTransforms integrating with Google Cloud AI - VideoIntelligence service. Converts GCS URIs of videos or ByteStrings with video contents into Lists of VideoAnnotationResults.

Adding a side input of Maps of elements to VideoContext objects is allowed, so is using KVs of element and VideoContext as input.

Service account with proper permissions is required to use these transforms.
